THE FIELD OF THE INVENTION

The present invention is in the field of soybean cultivar breeding anddevelopment. The present invention particularly relates to the soybeancultivar CS1660404 and/or CS1763636 and its seed, cells, germplasm,plant parts, and progeny, and its use in a breeding program.

BACKGROUND OF THE INVENTION

Soybean Glycine max (L) is an important oil seed crop and a valuablefield crop. However, it began as a wild plant. This plant and a numberof other plants have been developed into valuable agricultural cropsthrough years of breeding and development. The pace of the developmentof soybeans, into an animal foodstuff and as an oil seed hasdramatically increased in the last one hundred years. Planned programsof soybean breeding have increased the growth, yield and environmentalhardiness of the soybean germplasm.

Due to the sexual reproduction traits of the soybean, the plant isbasically self-pollinating. A self-pollinating plant permits pollen fromone flower to be transferred to the same or another flower of the sameplant. Cross-pollination occurs when the flower is pollinated withpollen from a different plant; however, soybean cross-pollination is arare occurrence in nature.

Thus the growth and development of new soybean germplasm requiresintervention by the breeder into the pollination of the soybean. Thebreeders' methods of intervening depends on the type of trait that isbeing bred. Soybeans are developed for a number of different types oftraits including morphology (form and structure), phenotypiccharacteristics, and for traits like growth, day length, relativematurity, temperature requirements, initiation date of floral orreproductive development, fatty acid content, insect resistance, diseaseresistance, nematode resistance, fungal resistance, herbicideresistance, tolerance to various environmental factors like drought,heat, wet, cold, wind, adverse soil condition and also for yield. Thegenetic complexity of the trait often drives the selection of thebreeding method.

Due to the number of genes within each chromosome, millions of geneticcombinations exist in the breeders' experimental soybean material. Thisgenetic diversity is so vast that a breeder cannot produce the same twocultivars twice using the exact same starting parental material. Thus,developing a single variety of useful commercial soybean germplasm ishighly unpredictable, and requires intensive research and development.

The development of new soybeans comes through breeding techniques, suchas: recurrent selection, mass selections, backcrossing, single seeddescent and multiple seed procedure. Additionally, marker assistedbreeding allows more accurate movement of desired alleles or evenspecific genes or sections of chromosomes to be moved within thegermplasm that the breeder is developing. RFLP, RAPD, AFLP, SSR, SNP,SCAR, and isozymes are some of the forms of markers that can be employedin breeding soybeans or in moving traits into soybean germplasm. Otherbreeding methods are known and are described in various plant breedingor soybean textbooks.

When a soybean variety is being employed to develop a new soybeanvariety or an improved variety, the selection methods may includebackcrossing, pedigree breeding, recurrent selection, marker assistedselection, modified selection and mass selection or a combination ofthese methods. The efficiency of the breeding procedure along with thegoal of the breeding are the main factors for determining whichselection techniques are employed. A breeder continuously evaluates thesuccess of the breeding program and therefore the efficiency of anybreeding procedures. The success is usually measured by yield increase,commercial appeal and environmental adaptability of the developedgermplasm.

The development of new soybean cultivars most often requires thedevelopment of hybrid crosses (some exceptions being initial developmentof mutants directly through the use of the mutating agent, certainmaterials introgressed by markers, or transformants made directlythrough transformation methods) and the selection of progeny. Hybridscan be achieved by manual manipulation of the sexual organs of thesoybean or by the use of male sterility systems. Breeders often try toidentify true hybrids by a readily identifiable trait or the visualdifferences between inbred and hybrid material. These heterozygoushybrids are then selected and repeatedly selfed and reselected to formnew homozygous soybean lines.

Mass and recurrent selection can be used to improve populations. Severalparents are intercrossed and plants are selected based on selectedcharacteristics like superior yield or excellent progeny resistance.Outcrossing to a number of different parents creates fairly heterozygousbreeding populations.

Pedigree breeding is commonly used with two parents that possessfavorable, complementary traits. The parents are crossed to form a F1hybrid. The progeny of the F1 hybrid is selected and the best individualF2s are selected; this selection process is repeated in the F3 and F4generations. The inbreeding is carried forward and at approximatelyF5-F7 the best lines are selected and tested in the development stagefor potential usefulness in a selected geographic area.

In backcross breeding a genetic allele or loci is often transferred intoa desirable homozygous recurrent parent. The trait from the donor parentis tracked into the recurrent parent. The resultant plant is bred to beessentially the same as the recurrent parent, with the same physiologyand morphological characteristics as the recurrent part, with the newdesired allele or loci.

The single-seed descent method involves use of a segregating plantpopulation for harvest of one seed per plant. Each seed sample isplanted and the next generation is formed. When the F2 lines areadvanced to approximately F6 or so, each plant will be derived from adifferent F2. The population will decline due to failure of some seeds,so not all F2 plants will be represented in the progeny.

New varieties must be tested thoroughly to compare their developmentwith commercially available soybeans. This testing usually requires atleast two years and up to six years of comparisons with other commercialsoybeans. Varieties that lack the entire desirable package of traits canbe used as parents in new populations for further selection or aresimply discarded. The breeding and associated testing process is 8 to 12years of work prior to development of a new variety. Thousands ofvarietal lines are produced but only a few lines are selected in eachstep of the process. Thus the breeding system is like a funnel withnumerous lines and selections in the first few years and fewer and fewerlines in the middle years until one line is selected for the finaldevelopment testing.

The selected line or variety will be evaluated for its growth,development and yield. These traits of a soybean are a result of thevariety's genetic potential interacting with its environment. Allvarieties have a maximum yield potential that is predetermined by itsgenetics. This hypothetical potential for yield is only obtained whenthe environmental conditions are near perfect. Since perfect growthconditions do not exist, field experimentation is necessary to providethe environmental influence and to measure its effect on the developmentand yield of the soybean. The breeder attempts to select for an elevatedsoybean yield potential under a number of different environmentalconditions.

Selecting for good soybean yield potential in different environmentalconditions is a process that requires planning based on the analysis ofdata in a number of seasons. Identification of the varieties carrying asuperior combination of traits, which will give consistent yieldpotential, is a complex science. The desirable genotypic traits in thevariety can often be masked by other plant traits, unusual weatherpatterns, diseases, and insect damage. One widely employed method ofidentifying a superior plant with such genotypic traits is to observeits performance relative to commercial and experimental plants inreplicated studies. These types of studies give more certainty to thegenetic potential and usefulness of the plant across a number ofenvironments.

In summary, the goal of the soybean plant breeder is to produce new andunique soybeans and progeny of the soybeans for farmers' commercial cropproduction.

To accomplish this, the plant breeder painstakingly crosses two or morevarieties or germplasm. Then the results of this cross are repeatedlyselfed or backcrossed to produce new genetic patterns. Newer avenues forproducing new and unique genetic alleles in soybeans include introducing(or creating) mutations or transgenes into the genetic material of thesoybean are now in practice in the breeding industry. These geneticalleles can alter pest resistance such as disease resistance, insectresistance, nematode resistance, herbicide resistance, or they can alterthe plant's environmental tolerances, or its seeds fatty acidcompositions, the amount of oil produced, and/or the amino acid/proteincompositions of the soybean plant or its seed.

The traits a breeder selects for when developing new soybeans are drivenby the ultimate goal of the end user of the product. Thus if the goal ofthe end user is to resist a certain plant disease so overall more yieldis achieved, then the breeder drives the introduction of genetic allelesand their selection based on disease resistant levels shown by theplant. On the other hand, if the goal is to produce specific fatty acidcomposition, with for example a high level of oleic acid and/or a lowerlevel of linolenic acid, then the breeder may drive the selection ofgenetic alleles/genes based on inclusion of mutations or transgenes thatalter the levels of fatty acids in the seed. Reaching this goal mayallow for the acceptance of some lesser yield potential or other lessdesirable agronomic trait.

The new genetic alleles being introduced into soybeans are widening thepotential uses and markets for the various products and by-products ofthe oil from seed plants such as soybean. A major product extracted fromsoybeans is the oil in the seed. Soybean oil is employed in a number ofretail products such as cooking oil, baked goods, margarines and thelike. Another useful product is soybean meal, which is a component ofmany foods and animal feedstuffs.

Trait Definitions

Hypocotyl Length (Hyp_R) A rating of a variety's hypocotyl extensionafter germination when planted at a 5″ depth in sand and maintained in awarm germination environment for 10 days.

Leaf Shape Calculated A calculated trait that divides length by widthamongst 5 different leaf samples per replicate, measured in cm.1=lanceolate; 2=oval; 3=ovate.

Seedling Establishment (EMRGR) A rating of uniform establishment andgrowth of seedlings. Rating is taken between the V1 and V3 growth stagesand is a 1 to 9 rating with 1 being the best stand establishment.

Seed Coat Peroxidase (Perox)—seed protein peroxidase activity is achemical taxonomic technique to separate cultivars based on the presenceor absence of the peroxidase enzyme in the seed coat. Ratings arePOS=positive for peroxidase enzyme or NEG=negative for peroxidaseenzyme. Ratings may also refer to the activity level of the seed proteinperoxidase. 1=low activity; 2=high activity.

Chloride Sensitivity (CLS_T) An “Excluder” accumulates chloride andrestricts the chloride in the roots. An “Includer” accumulates chloridethroughout the plant. Based on molecular markers for analyzing chloridesensitivity, a chloride excluder carries a susceptible marker allele,and a chloride includer has a resistant allele.

Plant Height (PLHTN) The average measured plant height, in centimeters,of 5 uniform plants per plot, taken just prior to harvest.

Plant Branching (PLBRR) Rating of the number of branches and theirrelative importance to yield. This rating is taken at growth expressivelocations. 1=no branching, 5=average and 9=profuse. Ratings taken justprior to harvest.

Green Lodging (GLDGR) Rating based on the average of plants leaning fromvertical at the R5 to R6 growth stage. 1=all are erect, 5=averageerectness. 9=all are flat. Rating of one is the best rating.

Harvest Lodging (HLDGR) Rating based on the average of plants leaningfrom vertical at harvest. Lodging score (1=completely upright, 5=45degree angle from upright; 9=completely prostrate). Rating one is thebest rating and ratings are taken just prior to harvest.

MON89788 The transgenic soybean event MON89788 carries a glyphosatetolerance transgene (U.S. Pat. No. 7,632,985 herein incorporated byreference). This transgene may be introgressed into a soybean variety,such that said variety now carries a glyphosate tolerance transgene.

MON87708 The transgenic soybean event MON87708 carries a transgene whichexpresses a dicamba mono-oxygenase, which confers tolerance todicamba-based herbicides. This transgene may be introgressed into asoybean variety, such that said variety now carries a dicamba tolerancetransgene.

Phytophthora Root Rot (PRR_R) means a Phytophthora Root Rot fieldtolerance rating. Rating is 1-9 with one being the best. The informationcan also include the listing of the actual resistance gene (RPS_T), forexample, Rps gene 1C.

Root Knot Nematode (RKN) Greenhouse screen—45 day screen of rootsinoculated with eggs and juveniles. Rating Scale based upon femalereproduction index on a susceptible check set determined by number ofgalls present on the root mass. Rating scale is 1-9 with 1 being best.Species specific ratings: Arenaria (MA_R), Incognita (MI_R), Javanica(MJ_R).

Stem Canker (Southern) (DPM_R) Greenhouse screen to identify vertical(gene) type of resistance. One week old soybean seedlings are inoculatedwith the stem canker pathogen by opening up a small slit into thehypocotyl and depositing a small drop of the fungal suspension. Theinoculated seedlings are then placed into a moisture chamber. When theseedlings of the known checks have collapsed, disease severity ratingare given on a 1-9 score. One being the best.

Stem canker (Southern) tolerance (DPMTR) Field nursery. The objective ofthis test is to evaluate the Field Resistance/Tolerance of soybean linesunder field conditions. This is necessary due to the fact that of thefour known genes that convey vertical type of resistance to stem canker,one gene (Rdc4 from the variety Dowling), exhibits a 40-50% plant kill(false positive) when screened in the greenhouse using the hypocotylinoculation technique. Lines that scored a rating of 4-9 in thegreenhouse are planted in the field. They are sprayed at least 5 timesduring their first month of development with a spore suspensioncontaining the stem canker fungus. With the inclusion of verysusceptible stem canker checks, we are able to identify horizontal(field resistance/tolerance) resistance in certain lines. Quite often,lines scoring a 9 in the greenhouse, rate a score of 1 in the field dueto either having the Rdc4 gene or having good fieldresistance/tolerance. Disease severity scores are once again given on a1-9 scale when the plants have reached the R6 growth stage of plantdevelopment. One being the best.

Brown Stem Rot (BSR_R) This disease is caused by the fungus Phialophoragregata. The disease is a late-season, cool-temperature, soil bornefungus which in appropriate favorable weather can cause up to 30 percentyield losses in soybean fields. BSR_R is an opportunistic field rating.The scale is 1-9. One rating is best.

Sudden Death Syndrome (SDS_R) This disease is caused by slow-growingstrains of Fursarium solani that produce bluish pigments in the centralpart of the culture when produced on a PDA culture. The disease appearsmainly in the reproductive growth stages (R2-R6) of soybeans. Normaldiagnostics are distinctive scattered, intervienal chlorotic spots onthe leaves. Yield losses may be total or severe in infected fields. TheSudden Death Syndrome Rating is both a field nursery and anopportunistic field rating. It is based on leaf area affected as definedby the Southern Illinois University method of SDS scoring. The scaleused for these tests is 1-9. A one rating is best.

Sclerotinia White Mold (SCL_R) This disease is caused by the fungalpathogen Sclerotinia sclerotium. The fungus can overwinter in the soilfor many years as sclerotia and infect plants in prolonged periods ofhigh humidity or rainfall. Yield losses may be total or severe ininfected fields. Sclerotinia White Mold (SCL_R) rating is a field rating(1-9 scale) based on the percentage of wilting or dead plants in a plot.A one rating is the best.

Frog Eye Leaf Spot (FELSR) This is caused by the fungal pathogenCercospora sojina. The fungus survives as mycelium in infected seeds andin infested debris. With adequate moisture new leaves become infected asthey develop until all the leaves are infected. Yield losses may be upto 15% in severe infected fields. Frog Eye Leaf Spot (FELSR) rating is afield rating (1-9 scale) based on the percentage of leaf area affected.The scale is 1-9 where 1=no leaf symptoms and 9=severe leaf symptoms.One is the best rating. To test varieties for Frog Eye Leaf Spot adisease nursery is artificially inoculated with spores. The ratings aredone when the plants have reached the R5-R6 growth stage. Visualcalibration is done with leaf photos of different frogeye severityratings as used by the University of Tennessee and Dr. Melvin Newman,State Plant Pathologist for TN.

Soybean Cyst Nematode (SCN) The Soybean Cyst Nematode Heteroderaglycines, is a small plant-parasitic roundworm that attacks the roots ofsoybeans. Soybean Cyst Nematode Ratings are taken from a 30 daygreenhouse screen using cyst infested soil. The rating scale is basedupon female reproduction index (F %) on a susceptible check set ((femalereproduction on a specific line/female reproduction on Susceptiblecheck)*100) where <10%=R (RESISTANT); >10%-<30%=MR (MODERATELYRESISTANT); >30%-<60%=MS (MODERATELY SUSPECTIBLE); >60%=S (SUSPECTIBLE).The screening races include: 1, 3, 5, 14. Individual ratings CN1_P,CN3_P, CN5_P, and CN14_P refer to the resistance to SCN races 1, 3, 5and 14 FI % respectively.

Powdery Mildew The name given to a group of diseases caused by severalclosely related fungi. Their common symptom is a grayish-white, powderymat visible on the surface of leaves, stems, and flower petals. Thereare many hosts; and although this disease is not considered fatal, plantdamage can occur when the infestation is severe.

Soybean Rust (Rust) Previously known as Asian soybean rust. This diseaseis caused by the fungus Phakopsora pachyrhiz.

Maturity Days from Planting (MRTYN) Plants are considered mature when95% of the pods have reached their mature color. MRTYN is the number ofdays calculated from planting date to 95% mature pod color.

Relative Maturity Group (RM) Industry Standard for varieties groups,based on day length or latitude. Long day length (northern areas in theNorthern Hemisphere) are classified as (Groups 000,00,0). Mid daylengths variety groups lie in the middle group (Groups I-VI). Very shortday lengths variety groups (southern areas in Northern Hemisphere) areclassified as (Groups VII, VIII, IX). Within a maturity group aresub-groups. A sub-group is a tenth of a relative maturity group (forexample, 1.3 would indicate a group 1 and a subgroup 3). Within narrowcomparisons, the difference of a tenth of a relative maturity groupequates very roughly to a day difference in maturity at harvest.

Grain Yield at Standard Moisture (YGSMN) The actual grain yield atstandard moisture (13%) reported in the unit's bushels/acre.

Shattering (STR_R) The rate of pod dehiscence prior to harvest. Poddehiscence is the process of beans dropping out of the pods. Advancedvarieties are planted in a replicated nursery south of their adaptedzone to promote early senescence. Mature plots are allowed to stand inthe field to endure heat/cool and especially wet/dry cycles. Rating isbased on the differences between varieties of the amount of open podsand soybeans that have fallen on the ground. The rating scale is 1-9with 1=no shattering and 9=severe shattering. One rating is best.

Definitions of Staging of Development

The plant development staging system employed in the testing of thisinvention divides stages as vegetative (V) and reproductive (R). Thissystem accurately identifies the stages of any soybean plant. However,all plants in a given field will not be in the stage at the same time.Therefore, each specific V or R stage is defined as existing when 50% ormore of the plants in the field are in or beyond that stage.

The first two stages of V are designated a VE (emergence) and VC(cotyledon stage). Subdivisions of the V stages are then designatednumerically as V1, V2, V3 through V (n). The last V stage is designatedas V (n), where (n) represents the number for the last node stage of thespecific variety. The (n) will vary with variety and environment. Theeight subdivisions of the reproductive stages (R) states are alsodesignated numerically. R1=beginning bloom; R2=full bloom; R3=beginningpod; R4=full pod; R5=beginning seed; R6=full seed; R7=beginningmaturity; R8=full maturity.

Soybean Cultivar CS1660404 and CS1763636

The present invention comprises a soybean plant, plant part, plant cell,and seed, characterized by molecular and physiological data obtainedfrom the representative sample of said variety deposited with theAmerican Type Culture Collection. Additionally, the present inventioncomprises a soybean plant comprising the homozygous alleles of thevariety, formed by the combination of the disclosed soybean plant orplant cell with another soybean plant or cell.

This soybean variety in one embodiment carries one or more transgenes,for example, the glyphosate tolerance transgene, a dicambamono-oxygenase gene, a desaturase gene or other transgenes. In anotherembodiment of the invention, the soybean does not carry any herbicideresistance traits. In yet another embodiment of the invention, thesoybean does not carry any transgenes but may carry alleles for aphidresistance, cyst nematode resistance and/or brown stem rot or the like.

The present invention provides methods and composition relating toplants, seeds and derivatives of the soybean cultivar CS1660404 and/orCS1763636. Soybean cultivar CS1660404 and/or CS1763636 has superiorcharacteristics. The CS1660404 and/or CS1763636 line has been selfedsufficient number of generations to provide a stable and uniform plantvariety.

Cultivar CS1660404 and/or CS1763636 shows no variants other thanexpected due to environment or that normally would occur for almost anycharacteristic during the course of repeated sexual reproduction. Someof the criteria used to select in various generations include: seedyield, emergence, appearance, disease tolerance, maturity, plant height,and shattering data.

The inventor(s) believe that CS1660404 and/or CS1763636 is similar inrelative maturity to the comparison varieties. However, as shown in thetables and as described, CS1660404 and/or CS1763636 differs from thesecultivars.

Direct comparisons were made between CS1660404 and/or CS1763636 and thelisted non-commercial or commercial varieties. Traits measured mayinclude yield, maturity, lodging, plant height, branching, fieldemergence, and shatter. The results of the comparison are presented inthe following tables. The number of tests in which the varieties werecompared is shown with the environments, mean and standard deviation forsome traits.

It is well known in the art that, by way of backcrossing, one or moretraits or loci may be introduced into a given variety while otherwiseretaining essentially all of the traits of that variety. An example ofsuch backcrossing to introduce a trait into a starting variety isdescribed in U.S. Pat. No. 6,140,556, where soybean variety Williams '82was developed using backcrossing techniques to transfer a locuscomprising the Rps1 gene to the variety Williams. Williams '82 iscomparable to the recurrent parent variety Williams except forresistance to phytopthora rot. Both Williams '82 and Williams have thesame relative maturity, indeterminate stems, and flower, pod,pubescence, and hilum color.

CS1660404 and/or CS1763636, or progeny thereof, can carry geneticengineered recombinant genetic material to give improved traits orqualities to the soybean. For example, but not limited to, CS1660404and/or CS1763636, or progeny thereof, can carry the glyphosateresistance gene for herbicide resistance as taught in the Monsantopatents (WO92/00377, WO92/04449, U.S. Pat. Nos. 5,188,642 and5,312,910), or a gene which confers tolerance to dicamba-basedherbicides, or the STS mutation for herbicide resistance. Additionaltraits carried in transgenes or mutation can be transferred intoCS1660404 and/or CS1763636, or progeny thereof. Some of these genesinclude genes that give disease resistance to sclerotinia such as theoxalate oxidase (Ox Ox) gene as taught in PCT/FR92/00195 Rhone Poluncand/or an oxalate decarboxylase gene for disease resistance or genesdesigned to alter the soybean oil within the seed such as desaturase,thioesterase genes (shown in EP0472722, U.S. Pat. No. 5,344,771) orgenes designed to alter the soybean's amino acid characteristics. Thisline can be crossed with another soybean line which carries a gene thatacts to provide herbicide resistance or alter the saturated and/orunsaturated fatty acid content of the oil within the seed, or the aminoacid profile of the seed. Thus through transformation or backcrossing ofCS1660404 and/or CS1763636, or progeny thereof, with a transgenic linecarrying the desired event, the present invention further comprise a newtransgenic event that is heritable. Some of the available soybeantransgenic events include 11-234-01p Dow Soybean 2, 4-D, Glyphosate andGlufosinate Tolerant/DAS-444Ø6-6; 11-202-01p Monsanto Soybean IncreasedYield/MON 87712; 10-188-01p Monsanto Soybean Dicamba Tolerant/MON 87708;09-015-01p BASF Soybean Imadazolinone Tolerant/BPS-CV127-9; 09-328-01pBayer Soybean Glyphosate and Isoxaflutole Tolerant/FG72; 09-201-01pMonsanto Soybean Improved Fatty Acid Profile/MON 87705; 09-183-01pMonsanto Soybean Stearidonic Acid Produced/MON 87769; 09-082-01pMonsanto Soybean Insect Resistant/MON 87701; 06-354-01p Pioneer SoybeanHigh Oleic Acid/Event 305423; 06-271-01p Pioneer Soybean Glyphosate &Acetolactate Synthase Tolerant/DP-356043-5; 06-178-01p Monsanto SoybeanGlyphosate Tolerant/MON 89788; 98-238-01p AgrEvo SoybeanPhosphinothricin Tolerant/GU262; 97-008-01p Du Pont Soybean High OleicAcid Oil/G94-1, G94-19, G-168; 96-068-01p AgrEvo Soybean GlufosinateTolerant/W62, W98, A2704-12, A2704-21, A5547-35; 96-068-01p AgrEvoSoybean Glufosinate Tolerant/W62, W98, A2704-12, A2704-21, A5547-35;93-258-01p Monsanto Soybean Glyphosate Tolerant/4-30-2.

CS1660404 and/or CS1763636, or progeny thereof, can also carry herbicidetolerance where the tolerance is conferred to an herbicide selected fromthe group consisting of glyphosate, glufosinate, acetolactate synthase(ALS) inhibitors, hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors,protoporphyrinogen oxidase (PPO) inhibitors, phytoene desaturase (PDS)inhibitors, photosystem II (PSII) inhibitors, dicamba and 2,4-D.

This invention also is directed to methods for producing a new soybeanplant by crossing a first parent plant with a second parent plantwherein the first or second parent plant is CS1660404 and/or CS1763636,or progeny thereof. Additionally, the present invention may be used inthe variety development process to derive progeny in a breedingpopulation or crossing. Further, both first and second parent plants canbe or be derived from the soybean line CS1660404 and/or CS1763636. Avariety of breeding methods can be selected depending on the mode ofreproduction, the trait, the condition of the germplasm. Thus, any suchmethods using the CS1660404 and/or CS1763636 are part of this invention:selfing, backcrosses, locus conversion, recurrent selection, massselection and the like.

The scope of the present invention includes use of marker methods. Inaddition to phenotypic observations, the genotype of a plant can also beexamined. There are many techniques or methods known which are availablefor the analysis, comparison and characterization of plant's genotypeand for understanding the pedigree of the present invention andidentifying plants that have the present invention as an ancestor; amongthese are Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), and Simple SequenceRepeats (SSRs) which are also referred to as Microsatellites.

A genotypic profile of soybean variety CS1660404 and/or CS1763636 can beused to identify a plant comprising variety CS1660404 and/or CS1763636as a parent, since such plants will comprise the same homozygous allelesas variety CS1660404 and/or CS1763636. Because the soybean variety isessentially homozygous at all relevant loci, most loci should have onlyone type of allele present. In contrast, a genetic marker profile of anF1 progeny should be the sum of those parents, e.g., if one parent washomozygous for allele X at a particular locus, and the other parenthomozygous for allele Y at that locus, then the F1 progeny will be XY(heterozygous) at that locus. Subsequent generations of progeny producedby selection and breeding are expected to be of genotype XX(homozygous), YY (homozygous), or XY (heterozygous) for that locusposition. When the F1 plant is selfed or sibbed for successive filialgenerations, the locus should be either X or Y for that position.

In addition, plants and plant parts substantially benefiting from theuse of variety CS1660404 and/or CS1763636 in their development, such asvariety CS1660404 and/or CS1763636 comprising a backcross conversion,locus conversion, transgene, or genetic sterility factor, may beidentified by having a molecular marker profile with a high percentidentity to soybean variety CS1660404 and/or CS1763636. Such a percentidentity might be 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%,99.5% or 99.9% identical to soybean variety CS1660404 and/or CS1763636.

A genotypic profile of variety CS1660404 and/or CS1763636 also can beused to identify essentially derived varieties and other progenyvarieties developed from the use of variety CS1660404 and/or CS1763636,as well as cells and other plant parts thereof. Plants of the inventioninclude any plant having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%,97%, 98%, 99%, 99.5%, or 99.9% of the markers in the genotypic profile,and that retain 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%,or 99.9% of the morphological and physiological characteristics ofvariety CS1660404 and/or CS1763636 when grown under the same conditions.Such plants may be developed using markers well known in the art.Progeny plants and plant parts produced using variety CS1660404 and/orCS1763636 may be identified, for example, by having a molecular markerprofile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%,75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%,89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 99.5% geneticcontribution from soybean variety CS1660404 and/or CS1763636, asmeasured by either percent identity or percent similarity. Such progenymay be further characterized as being within a pedigree distance ofvariety CS1660404 and/or CS1763636, such as within 1, 2, 3, 4, or 5 orless cross pollinations to a soybean plant other than variety CS1660404and/or CS1763636, or a plant that has variety CS1660404 and/or CS1763636as a progenitor. Unique molecular profiles may be identified with othermolecular tools, such as SNPs and RFLPs.

The present invention also includes methods of isolating nucleic acidsfrom a plant, a plant part, or a seed of the soybean variety of theinvention, analyzing said nucleic acids to produce data, and recordingsaid data. In some embodiments, the data may be recorded on a computerreadable medium. The data may comprise a nucleic acid sequence, a markerprofile, a haplotype, or any combination thereof. In some embodiments,the data may be used for crossing, selection, or advancement decisionsin a breeding program.

A backcross conversion, locus conversion, transgene, or geneticsterility factor, may be in an embodiment of the present invention.Markers can be useful in their development, such that the presentinvention comprising backcross conversion(s), transgene(s), or geneticsterility factor(s), and are identified by having a molecular markerprofile with a high percent identity such as 95%, 96%, 97%, 98%, 99%,99.5% or 99.9% identical to CS1660404 and/or CS1763636.

These embodiments may be detected using measurements by either percentidentity or percent similarity to the deposited material. These markersmay detect progeny plants identifiable by having a molecular markerprofile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%,75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%,89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% geneticcontribution from an embodiment of CS1660404 and/or CS1763636. Suchprogeny may be further characterized as being within a pedigree distanceof 1, 2, 3, 4 or 5 or more cross-pollinations to a soybean plant otherthan the CS1660404 and/or CS1763636 or a plant that has CS1660404 and/orCS1763636 as a progenitor. Molecular profiles may be identified withSNP, Single Nucleotide Polymorphism, or other tools also.

Traits are average values for all trial locations, across all years inwhich the data was taken. In addition to the visual traits that aretaken, the genetic characteristic of the plant can also be characterisedby its genetic marker profile. The profile can interpret or predict thepedigree of the line, the relation to another variety, determine theaccuracy of a listed breeding strategy, or invalidate a suggestedpedigree. Soybean linkage maps were known by 1999 as evidenced in Creganet. al, “An Integrated Genetic Linkage Map of the Soybean Genome” CropScience 39:1464 1490 (1999); and using markers to determine pedigreeclaims was discussed by Berry et al., in “Assessing Probability ofAncestry Using Simple Sequence Repeat Profiles: Applications to MaizeInbred Lines and Soybean Varieties” Genetics 165:331 342 (2003), each ofwhich are incorporated by reference herein in their entirety. Markersinclude but are not limited to Restriction Fragment Length Polymorphisms(RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily PrimedPolymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting(DAF), Sequence Characterized Amplified Regions (SCARs), AmplifiedFragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs)which are also referred to as Microsatellites, and Single NucleotidePolymorphisms (SNPs). There are known sets of public markers that arebeing examined by ASTA and other industry groups for their applicabilityin standardizing determinations of what constitutes an essentiallyderived variety under the US Plant Variety Protection Act. However,these standard markers do not limit the type of marker and markerprofile which can be employed in breeding or developing backcrossconversions, or in distinguishing varieties or plant parts or plantcells, or verify a progeny pedigree. Primers and PCR protocols forassaying these and other markers are disclosed in the Soybase (sponsoredby the USDA Agricultural Research Service and Iowa State University)located at the world wide web at 129.186.26.94/SSR.html.

Additionally, these markers such as SSRs, RFLP's, SNPs, Ests, AFLPs,gene primers, and the like can be developed and employed to identifygenetic alleles which have an association with a desired trait, loci orlocus. The allele can be used in a marker assisted breeding program tomove traits (native, nonnative (from a different species), ortransgenes) into CS1660404 and/or CS1763636, or progeny thereof. Thevalue of markers includes allowing the introgression and/or locusconversion of the allele(s)/trait(s) into the desired germplasm withlittle to no superfluous germplasm being dragged from the allele/traitdonor plant into CS1660404 and/or CS1763636, or progeny thereof. Thisresults in formation of, for example, cyst nematode resistance, brownstem rot resistance, aphid resistance, Phytophthora resistance, IDCresistance, BT genes, male sterility genes, glyphosate tolerance genes,Dicamba tolerance, HPPD tolerance, rust tolerance, Asian Rust tolerance,fungal tolerance, or drought tolerance genes. Additionally, CS1660404and/or CS1763636, or progeny thereof, through transgenes, or if a nativetrait through markers or backcross breeding, can include apolynucleotide encoding phytase, FAD-2, FAD-3, galactinol synthase or araffinose synthetic enzyme; or a polynucleotide conferring resistance tosoybean cyst nematode, brown stem rot, phytophthora root rot, or suddendeath syndrome or resistance, tolerance to FUNGAL DISEASES such as:Alternaria spp., Agrobacterium rhizogenes, Calonectria crotalariae,Cercospora kikuchii, Cercospora sojina, Choanephora infundibulifera,Colletotrichum spp., Corynespora cassiicola, Curtobacteriumflaccumfaciens, Dactuliochaeta glycines, Diaporthe phaseolorum, Fusariumoxysporum, Macrophomina phaseolina, Microsphaera difusa, Peronosporamanshurica, Phakopsora pachyrhizi, Phialophora gregata, Phomopsisphaseolorum, Phyllosticta sojicola, Phytophthora sojae, Pseudomonassyringae, Pythium spp., Rhizoctonia solana, Sclerotinia sclerotiorum,Sclerotium rolfsii, Septoria glycines, Sphaceloma glycines,Thielaviopsis basicota; or tolerance to BACTERIAL and VIRAL DISEASESsuch as: Xanthomonas campestres, Cowpea Chlorotic Mottle Virus (CCMV),Peanut Mottle Virus (PMV), Tobacco Streak Virus (TSV), Bean YellowMosaic Virus (BYMV), Black Gram Mottle Virus (BGMV), Cowpea Mild MottleVirus (CMMV), Cowpea Severe Mosaic Virus (CSMV), Indonesian SoybeanDwarf Virus (ISDV), Mung Bean Yellow Mosaic Virus (MYMV), Peanut StripeVirus (VPMM), Soybean Chlorotic Mottle Virus, Soybean Crinkle LeafVirus, Soybean Yellow Vein Virus (SYVV), Tobacco Mosaic Virus (TMV);NEMATODES such as: Belonolaimus gracilis, Meloidogyne spp, Rotylenchulusreniformis, Pratylenchus spp., Hoplolaimus sulumbus, Heteroderaschachtii.

Many traits have been identified that are not regularly selected for inthe development of a new cultivar. Using materials and methods wellknown to those persons skilled in the art, traits that are capable ofbeing transferred, to a cultivar of the present invention include, butare not limited to, herbicide tolerance, resistance for bacterial,fungal, or viral disease, nematode resistance, insect resistance,enhanced nutritional quality, such as oil, starch and protein content orquality, improved performance in an industrial process, alteredreproductive capability, such as male sterility or male/femalefertility, yield stability and yield enhancement. Other traits includethe production of commercially valuable enzymes or metabolites withinthe present invention.

A transgene typically comprises a nucleotide sequence whose expressionis responsible or contributes to the trait, under the control of apromoter capable of directing the expression of the nucleotide sequenceat the desired time in the desired tissue or part of the plant.Constitutive, tissue-specific or inducible promoters are well known inthe art and have different purposes and each could be employed. Thetransgene(s) may also comprise other regulatory elements such as forexample translation enhancers or termination signals. The transgene maybe adapted to be transcribed and translated into a protein, or to encodeRNA in a sense or antisense orientation such that it is not translatedor only partially translated.

Transgenes may be directly introduced into the cultivar using geneticengineering, site specific insertion techniques, and transformationtechniques well known in the art or introduced into the cultivar througha process which uses a donor parent which has the transgene(s) alreadyintrogressed. This process of introduction of a transgene(s) ornative/non-native traits into the cultivar may use the donor parent in amarker assisted trait conversion process, where the trait may be movedfor example by backcrossing using the markers for selection ofsubsequent generations.

The laboratory-based techniques described above, in particular RFLP andSSR, can be used in such backcrosses to identify the progenies havingthe highest degree of genetic identity with the recurrent parent. Thispermits one to accelerate the production of soybean cultivars having atleast 90%, 95%, 99% genetic, or genetically identical to the recurrentparent, and further comprising the trait(s) introgressed from the donorparent. Such determination of genetic identity can be based on markersused in the laboratory-based techniques described above.

The last backcross generation is then selfed to give pure breedingprogeny for the gene(s) being transferred. The resulting plants haveessentially all of the morphological and physiological characteristicsof a cultivar of the present invention, in addition to the gene trait(s)transferred to the inbred. The exact backcrossing protocol will dependon the trait being altered to determine an appropriate testing protocol.Although backcrossing methods are simplified when the trait beingtransferred is a dominant allele, a recessive allele may also betransferred. In this instance it may be necessary to introduce a test ofthe progeny to determine if the desired trait has been successfullytransferred.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenome editing or modification. As an example, a genetically modifiedplant variety is generated using “custom” or engineered endonucleasessuch as meganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Umov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) elfector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al. (2011), Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system and Cas12a/guideRNA-based system, for example, allows targeted cleavage of genomic DNAguided by a customizable small noncoding RNA in plants (see e.g., WO2015026883A1 and WO2016205711A1, each incorporated herein by reference).

The cultivars of the invention can also be used for transformation whereexogenous genes are introduced and expressed by the cultivars of theinvention. Genetic variants created either through traditional breedingmethods using a cultivar of the present invention or throughtransformation of such cultivar by any of a number of protocols known tothose of skill in the art are intended to be within the scope of thisinvention (see e.g. Trick et al. (1997) Recent Advances in SoybeanTransformation, Plant Tissue Culture and Biotechnology, 3:9-26).

Transformation methods are means for integrating new genetic codingsequences (transgenes) into the plant's genome by the incorporation ofthese sequences into a plant through man's assistance. Many dicotsincluding soybeans can easily be transformed with Agrobacterium. Methodsof introducing desired recombinant DNA molecule into plant tissueinclude the direct infection or co-cultivation of plant cells withAgrobacterium tumefaciens, Horsch et al., Science, 227:1229 (1985).Descriptions of Agrobacterium vector systems and methods are shown inGruber, et al., “Vectors for Plant Transformation, in Methods in PlantMolecular Biology & Biotechnology” in Glich et al., (Eds. pp. 89-119,CRC Press, 1993). Transformed plants obtained via protoplasttransformation are also intended to be within the scope of thisinvention. Other transformation methods such as whiskers, aerosol beam,etc. are well known in the art and are within the scope of thisinvention. The most common method of transformation after the use ofAgrobacterium is referred to as gunning or microprojectile bombardment.This process has small gold-coated particles coated with DNA (includingthe transgene) shot into the transformable material. Techniques forgunning DNA into cells, tissue, explants, meristems, callus, embryos,and the like are well known in the prior art.

The DNA used for transformation of these plants clearly may be circular,linear, and double or single stranded.

Some of the time the DNA is in the form of a plasmid. The plasmid maycontain additional regulatory and/or targeting sequences which assistthe expression or targeting of the gene in the plant. The methods offorming plasmids for transformation are known in the art. Plasmidcomponents can include such items as: leader sequences, transitpolypeptides, promoters, terminators, genes, introns, marker genes, etc.The structures of the gene orientations can be sense, antisense, partialantisense or partial sense: multiple gene copies can be used.

After the transformation of the plant material is complete, the nextstep is identifying the cells or material, which has been transformed.In some cases, a screenable marker is employed such as thebeta-glucuronidase gene of the uidA locus of E. coli. Then, thetransformed cells expressing the colored protein are selected for eitherregeneration or further use. In many cases, a selectable markeridentifies the transformed material. The putatively transformed materialis exposed to a toxic agent at varying concentrations. The cells nottransformed with the selectable marker, which provides resistance tothis toxic agent, die. Cells or tissues containing the resistantselectable marker generally proliferate. It has been noted that althoughselectable markers protect the cells from some of the toxic effects ofthe herbicide or antibiotic, the cells may still be slightly affected bythe toxic agent by having slower growth rates. If the transformedmaterials are cell lines then these lines are used to regenerate plants.The cells' lines are treated to induce tissue differentiation. Methodsof regeneration of plants are well known in the art. General methods ofculturing plant tissues are provided for example by Maki et al.“Procedures for Introducing Foreign DNA into Plants” in Methods in PlantMolecular Biology & Biotechnology, Glich et al. (Eds. pp. 67-88 CRCPress, 1993); and by Phillips et al. “Cell-Tissue Culture and In-VitroManipulation” in Soybean & Soybean Improvement, 3rd Edition Sprague etal. (Eds. pp. 345-387) American Society of Agronomy Inc. et al. 1988.

The plants from the transformation process or the plants resulting froma cross using a transformed line or the progeny of such plants whichcarry the transgene are transgenic plants.

The genes responsible for a specific gene trait are generally inheritedthrough the nucleus. Known exceptions are, e.g. the genes for malesterility, some of which are inherited cytoplasmically, but still act assingle gene traits. Male sterile soybean germplasm for hybrid soybeanproduction was taught in U.S. Pat. No. 4,648,204. In a preferredembodiment, a transgene to be introgressed into the cultivar CS1660404and/or CS1763636 is integrated into the nuclear genome of the donor,non-recurrent parent or the transgene is directly transformed into thenuclear genome of cultivar CS1660404 and/or CS1763636. In anotherembodiment of the invention, a transgene to be introgressed intocultivar CS1660404 and/or CS1763636 is integrated into the plastidgenome of the donor, non-recurrent parent or the transgene is directlytransformed into the plastid genome of cultivar CS1660404 and/orCS1763636. In a further embodiment of the invention, a plastid transgenecomprises a gene that has transcribed from a single promoter, or two ormore genes transcribed from a single promoter.

In another embodiment of the invention, DNA sequences native to soybeanas well as non-native DNA sequences can be transformed into the soybeancultivar of the invention and used to alter levels of native ornon-native proteins. Various promoters, targeting sequences, enhancingsequences, and other DNA sequences can be inserted into the genome forthe purpose of altering the expression of proteins. Reduction of theactivity of specific genes (also known as gene silencing or genesuppression) is desirable for several aspects of genetic engineering inplants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to, knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook Ch.118 (Springer-Verlag 1994)); antisense technology (see, e.g., Sheehy etal. (1988) PNAS USA 85:8805-8809; and U.S. Pat. Nos. 5,107,065;5,453,566; and 5,759,829); co-suppression (e.g., Taylor (1997) PlantCell 9:1245; Jorgensen (1990) Trends Biotech 8:340-344; Flavell (1994)PNAS USA 91:3490-3496; Finnegan et al. (1994) Bio/Technology 12:883-888;and Neuhuber et al. (1994) Mol Gen Genet 244:230-241); RNA interference(Napoli et al. (1990) Plant Cell 2:279-289; U.S. Pat. No. 5,034,323;Sharp (1999) Genes Dev 13:139-141; Zamore et al. (2000) Cell 101:25-33;and Montgomery et al. (1998) PNAS USA 95:15502-15507); virus-inducedgene silencing (Burton et al. (2000) Plant Cell 12:691-705; Baulcombe(1999) Curr Op Plant Biol 2:109-113); target-RNA specific ribozymes(Flaselolf et al. (1988) Nature 334: 585-591); hairpin structures (Smithet al. (2000) Nature 407:319-320; WO99/53050; WO98/53083); microRNA(Aukerman & Sakai (2003) Plant Cell 15:2730-2741); ribozymes (Steineckeet al. (1992) EMBO J 11:1525; Perriman et al. (1993) Antisense Res Dev3:253); oligonucleotide mediated targeted modification (e.g, WO03/076574and WO99/25853); Zn-finger targeted molecules (e.g, WO01/52620;WO03/048345; and WOOO/42219); use of exogenously applied RNA (e.g,US20110296556); and other methods or combinations of the above methodsknown to those of skill in the art.

A non-exclusive list of traits or nucleotide sequences capable of beingtransferred into cultivar CS1660404 and/or CS1763636, for example bysingle locus conversion, using material and methods well known to thosepersons skilled in the art are as follows: genetic factor(s) responsiblefor resistance to brown stem rot (U.S. Pat. No. 5,689,035) or resistanceto cyst nematodes (U.S. Pat. No. 5,491,081); a transgene encoding aninsecticidal protein, such as, for example, a crystal protein ofBacillus thuringiensis or a vegetative insecticidal protein fromBacillus cereus, such as VIP3 (see, for example, Estruch et al. NatBiotechnol [1997] 15:137-41); a herbicide tolerance transgene whoseexpression renders plants tolerant to the herbicide, for example,expression of an altered acetohydroxyacid synthase (AHAS) enzyme confersupon plants tolerance to various imidazolinone or sulfonamide herbicides(U.S. Pat. No. 4,761,373.) Other traits capable of being transformedinto cultivar CS1660404 and/or CS1763636 include, for example, anon-transgenic trait conferring to cultivar CS1660404 and/or CS1763636tolerance to imidazolinones or sulfonylurea herbicides; a transgeneencoding a mutant acetolactate synthase (ALS) that renders plantsresistant to inhibition by sulfonylurea herbicides (U.S. Pat. No.5,013,659); a gene encoding a mutant glutamine synthetase (GS) resistantto inhibition by herbicides that are known to inhibit GS, e.g.phosphinothricin and methionine sulfoximine (U.S. Pat. No. 4,975,374);and a Streptomyces bar gene encoding a phosphinothricin acetyltransferase resulting in tolerance to the herbicide phosphinothricin orglufosinate (U.S. Pat. No. 5,489,520.)

Other genes capable of being transferred into the cultivar CS1660404and/or CS1763636 of the invention include tolerance to inhibition bycyclohexanedione and aryloxyphenoxypropanoic acid herbicides (U.S. Pat.No. 5,162,602), which is conferred by an altered acetyl coenzyme Acarboxylase (ACCase); transgenic glyphosate tolerant plants, whichtolerance is conferred by an altered 5-enolpyruvyl-3-phosphoshikimate(EPSP) synthase gene; tolerance to a protoporphyrinogen oxidaseinhibitor, which is achieved by expression of a tolerantprotoporphyrinogen oxidase enzyme in plants (U.S. Pat. No. 5,767,373.)Genes encoding altered protox resistant to a protox inhibitor can alsobe used in plant cell transformation methods. For example, plants, planttissue or plant cells transformed with a transgene can also betransformed with a gene encoding an altered protox (See U.S. Pat. No.6,808,904 incorporated by reference) capable of being expressed by theplant. The thus-transformed cells are transferred to medium containingthe protox inhibitor wherein only the transformed cells will survive.Protox inhibitors contemplated to be particularly useful as selectiveagents are the diphenylethers (e.g. acifluorfen,5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobezoic acid; its methylester, or oxyfluorfen,2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluorobenzene)), oxidiazoles,(e.g. oxidiazon,3-[2,4-dichloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2-(3H)-one),cyclic imides (e.g. S-23142,N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-3,4,5,6-tetrahydrophthalimide;chlorophthalim, N-(4-chlorophenyl)-3,4,5,6-tetrahydrophthalimide),phenyl pyrazoles (e.g. TNPP-ethyl, ethyl2-[1-(2,3,4-trichlorophenyl)-4-nitropyrazolyl-5-oxy]propionate; M&B39279), pyridine derivatives (e.g. LS 82-556), and phenopylate and itsO-phenylpyrrolidino- and piperidinocarbamate analogs and bicyclictriazolones as disclosed in the International patent application WO92/04827; EP 532146).

The method is applicable to any plant cell capable of being transformedwith an altered protox-encoding gene, and can be used with any transgeneof interest. Expression of the transgene and the protox gene can bedriven by the same promoter functional on plant cells, or by separatepromoters.

Modified inhibitor-resistant protox enzymes of the present invention areresistant to herbicides that inhibit the naturally occurring protoxactivity. The herbicides that inhibit protox include many differentstructural classes of molecules (Duke et al., Weed Sci. 39: 465 (1991);Nandihalli et al., Pesticide Biochem. Physiol. 43: 193 (1992); Matringeet al., FEBS Lett. 245: 35 (1989); Yanase and Andoh, Pesticide Biochem.Physiol. 35: 70 (1989)), including the diphenylethers {e.g.acifluorifen, 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobezoicacid; its methyl ester; or oxyfluorfen,2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluorobenzene)}, oxidiazoles(e.g. oxidiazon,3-[2,4-dichloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2-(3H)-one),cyclic imides (e.g. S-23142,N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-3,4,5,6-tetrahydrophthalimide;chlorophthalim, N-(4-chlorophenyl)-3,4,5,6-tetrahydrophthalimide),phenyl pyrazoles (e.g. TNPP-ethyl, ethyl2-[1-(2,3,4-trichlorophenyl)-4-nitropyrazolyl-5-oxy]propionate; M&B39279), pyridine derivatives (e.g. LS 82-556), and phenopylate and itsO-phenylpyrrolidino- and piperidinocarbamate analogs.

Direct selection may be applied where the trait acts as a dominanttrait. An example of a dominant trait is herbicide tolerance. For thisselection process, the progeny of the initial cross are sprayed with theherbicide prior to the backcrossing. The spraying eliminates any plantthat does not have the desired herbicide tolerance characteristic, andonly those plants that have the herbicide tolerance gene are used in thesubsequent backcross. This process is then repeated for the additionalbackcross generations.

In yet another embodiment of the present invention, a transgenetransformed or introgressed into cultivar CS1660404 and/or CS1763636,for example as a single locus conversion, comprises a gene conferringtolerance to a herbicide and at least another nucleotide sequence foranother trait, such as for example, insect resistance or tolerance toanother herbicide. Another gene capable of being transferred into thecultivar CS1660404 and/or CS1763636 of the invention expressesthioredoxin and thioredoxin reductase enzymes for modifying graindigestibility and nutrient availability (U.S. Pat. Appl. No.20030145347.)

Further reproduction of the cultivar can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well known and widely published. Forexample, reference may be had to Komatsuda, T. et al., “Genotype XSucrose Interactions for Somatic Embryogenesis in Soybean,” Crop Sci.31:333-337 (1991); Stephens, P.

Thus, anotheraspect of this invention is to provide cells that upon growth anddifferentiation produce soybean plants having all or essentially all thephysiological and morphological characteristics of cultivar CS1660404and/or CS1763636. The disclosures, publications, and patents that aredisclosed herein are all hereby incorporated herein in their entirety byreference.

Sublines of soybean variety CS1660404 and/or CS1763636 may also bedeveloped and are provided. Although soybean variety CS1660404 and/orCS1763636 contains substantially fixed genetics and is phenotypicallyuniform with no off types expected, there still remains a smallproportion of segregating loci either within individuals or within thepopulation as a whole. Sublining provides the ability to select forthese loci, which have no apparent morphological or phenotypic effect onthe plant characteristics, but may have an effect on overall yield. Forexample, the methods described in U.S. Pat. Nos. 5,437,697, 7,973,212,and US2011/0258733, and US2011/0283425 (each of which is hereinincorporated by reference) may be utilized by a breeder of ordinaryskill in the art to identify genetic loci that are associated with yieldpotential to further purify the variety in order to increase its yield.A breeder of ordinary skill in the art may fix agronomically relevantloci by making them homozygous in order to optimize the performance ofthe variety. The development of soybean sublines and the use ofaccelerated yield technology is a plant breeding technique.

The seed of soybean cultivar CS1660404 and/or CS1763636 furthercomprising one or more specific, single gene traits, the plant producedfrom the seed, the hybrid soybean plant produced from the crossing ofthe cultivar with any other soybean plant, hybrid seed, and variousparts of the hybrid soybean plant can be utilized for human food,livestock feed, and as a raw material in industry.

Industrial uses of soybean oil that is subjected to furtherprocessing include ingredients for paints, plastics, fibers, detergents,cosmetics, and lubricants. Soybean oil may be split, inter-esterified,sulfurized, epoxidized, polymerized, ethoxylated, or cleaved. Designingand producing soybean oil derivatives with improved functionality,oliochemistry is a rapidly growing field. The typical mixture oftriglycerides is usually split and separated into pure fatty acids,which are then combined with petroleum-derived alcohols or acids,nitrogen, sulfonates, chlorine, or with fatty alcohols derived from fatsand oils.

Soybean seeds, plants, and plant parts may be used or processed forfood, animal feed, or a raw material(s) for industry. Soybean is notjust a seed it is also used as a grain. Soybean is widely used as asource of protein for animal feeds for poultry, swine and cattle. Thesoybean grain is a commodity. The soybean commodity plant productsinclude but are not limited to protein concentrate, protein isolate,soybean hulls, meal, flower, oil and the whole soybean itself. Soybeanseeds can be crushed, or a component of the seeds can be extracted inorder to make a plant product, such as protein concentrate, proteinisolate, soybean hulls, meal, flour, or oil for a food or feed product.Methods of producing a plant product, such as protein concentrate,protein isolate, soybean hulls, meal, flour, or oil for a food or feedproduct are provided. Also provided are the protein concentrate, proteinisolate, soybean hulls, meal, flour, or oil produced by the methods.

Oil extracted from soybeans is used for cooking oil, margarine, andsalad dressings. Soybean oil has a typical composition of 11% palmitic,4% stearic, 25% oleic, 50% linoleic, and 9% linolenic fatty acidcontent. Industrial uses of soybean oil, which is typically subjected tofurther processing, include ingredients for paints, plastics, fibers,detergents, cosmetics, lubricants, and biodiesel fuel. Soybean oil maybe split, inter-esterified, sulfurized, epoxidized, polymerized,ethoxylated, or cleaved. To produce oil, the harvested soybeans arecracked, adjusted for moisture content, rolled into flakes, and then theoil is solvent-extracted. The oil extract is refined, optionally blendedand/or hydrogenated. Some soybean varieties have modified fatty acidprofiles and can be used to produce soybean oil with a modified fattyacid composition. Oil with 3% or less linolenic acid is classified aslow linolenic oil, oil with less than 1% linolenic acid is classified asultra low linolenic oil. Oil with 70% or higher of oleic acid isclassified as high oleic oil.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for animal feed. Thefibrous hull is removed from whole soybean and the oil is extracted. Theremaining meal is a combination of carbohydrates and approximately 50%protein. This remaining meal is heat treated under well-establishedconditions and ground in a hammer mill. Soybean is a predominant sourcefor livestock feed components. In addition to soybean meal, soybean canbe used to produce soy flour. Soy flour refers to defatted soybeanswhere special care was taken during desolventizing to minimize proteindenaturation and to retain a high nitrogen solubility index (NSI) inmaking the flour. Soy flour is the typical starting material forproduction of soy concentrate and soy protein isolate. Defatted soyflour is obtained from solvent extracted flakes, and contains less than1% oil. Full-fat soy flour is made from whole beans and contains about18% to 20% oil. Low-fat soy flour is made by adding back some oil todefatted soy flour. The lipid content varies, but is usually between4.5-9%. High-fat soy flour can also be produced by adding soybean oil todefatted flour at the level of 15%.

Lecithinated soy flour is made by adding soybean lecithin to defatted,low-fat or high-fat soy flours to increase dispersibility and impartemulsifying properties.

For human consumption, soybean can be used to produce edible ingredientswhich serve as an alternative source of dietary protein. Common examplesinclude milk, cheese, and meat substitutes. Additionally, soybean can beused to produce various types of fillers for meat and poultry products.Vitamins and/or minerals may be added to make soy products nutritionallymore equivalent to animal protein sources as the protein quality isalready roughly equivalent.
